Stratification

[riverculture]

Hi:

There is a technique called stratification for evaluation purpose, such as in cross-validation. I am wondering how I can incorporate stratification in the evaluation procedure in WEKA, or it has been built-in so that it will be executed automatically without extra intervention.

Thank you

Yep, weka's cross validation process has built-in stratification.

Cheers!
